C would be your answer it’s the only one with a total of 25 for the number of students that play an instrument

Answer:

Option: C is the correct answer.

The two-way frequency table is given as:

                                         Band            Not in Band       Total

Play instrument                    20                     5                   25

Do not play instrument        0                       15                 15

Total                                     20                      20                40

Step-by-step explanation:

We are given a survey of 40 students regarding whether they play an instrument or not.

We are given an information as:

1. 25 students play an instrument.

2. 20 students are in band.

3. 20 students are not in band

Hence, the table can be formed as:

                                          Band            Not in Band       Total

Play instrument                    20                     5                   25

Do not play instrument        0                       15                 15

Total                                     20                      20                40

( Since, those who don't play any instruments can't even play band hence the value of that in table is 0)
